COOKING-RANGE.

The-Schedule referred to in these Letters Patent: and making part of thesame.

nying drawings, and to the letters and marks thereon,

which said-drawings form part of this specification, and represent acooking-range, and parts thereof, with my improvements therein embraced-Figure 1 being a front view, in elevation, of such range;

Figure 2 being a view,by vertical section, on the red line of fig. 1;

Figure 3, a top view of the main part of the range, without theoven-portion;

Figure 4, a side view of one of the ovens detached;

Figure 5, a front view of one of the ovens, also detached.

In all of these-figures, where like points are shown, like marks andletters are used to indicate the parts. The range here shown is on theprinciple of base- -burning, with a supply-chamber or magazine.

A great difliculty to be overcome in base-burning in cooking-stoves, tokeep a continuous fire, and good.

condition for boiling, baking, &c., is to get rid of the cinders andslag without dumping out all the fuel, as you cannot grind out thecinders in an oblong or rectangular fire-chamber as you can in a roundfire-box I resort to these means for overcoming this difficulty:

First, I construct the front with a narrow grate, a, so fitted in andguided that it can be raised or lowered, and when raised will allow of apoker being introduced to rake the cinders out and permit them to fallinto the ash-pit.

- The form of. the grate b curving up at its back,

gives full scope to the poker, and of the bringing of the cindersforward.

My second means is a sliding plate or horizontal grate, c, with handles(1 in front, dividing the fuel above The back f of the fire-box isinclined upward and backward, as is also the back g of the magazine h,to

correspond, so that the coal may move toward the front, as the mouth ofthe magazine cannot well be. over the centre of the fire-chamber andgive space for the boilers to be over the fire.

The magazine It projects in front of the ovens, for allowing sufficientfacilities for supplying it with fuel.

Part of the magazine is under the oven-flue i, and. also forms part ofthe fines j to the ovens.

The ovens k are made of sheet-iron, with a castiron rim, 1,-to fit intothe recess m' of the oven front, the sheet-iron being riveted to thecast-rim. The ovens can, therefore, be'easily taken out to be cleaned orrepaired, and being of an oval form can easily be kept in proper shape.

An air-pipe, n, passes from the exterior, through the 'flues, to one orboth ovens, to supply heated air to the ovens, .to facilitate baking,and for ventilation of the ovens. p

The improvements here enumerated may be used in ranges to be set inbrick-work, or they may be used in cast-iron ranges complete withoutsuch setting.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The magazine, in combination with elevated ovens, substantially asset forth.

2. The location of the magazine between the fines to the elevated ovens.l

3. The construction of the front fire-box with the grate a, for removingthecinders, ashes, &c., in combination with a magazine, as hereinrecited.

4. In a range of the general construction herein shown, the arrangementherein set forth of the hori zontal sliding plate or grate, between thefuel, below the bottom of the magazine or fuel-reservoir, and the fuelin the dumping-grate, as and for the purposes recited.

5. The air-pipes n, and their location and application, substantially asdescribed.

6. The arrangement of the magazine in relation to the ovens hereindescribed, by which the" top of the magazine projects beyond the ovenfront orline of the ovens, for the purposes herein set forth.

This specification signed this 3d day of March, 1869.
